I'm going to be moving to Colorado soon and have been reading up on how low humidity environments effect guitars. I'm moving from California, which is has pretty consistent humidity, and am hoping that you all might be able to recommend products/ideas for taking care of guitars/amps. I'm primarily concerned about my electrics (PRS CE24 & an LP) as well as my amps (DR and JCM 800). I have hard cases for the electrics and so I'm planning on keeping them in their cases, but also would like to find something to help monitor humidity levels for them. I've heard that some people get humidifiers for their music rooms but I'm not sure if that's something I want running 24/7.

Also, should I be concerned about static building up inside of the amps? I've heard stories of people seeing 'arcs' when turning on even light switches so I can only imagine that I should exercise some sort of caution for my amps. Maybe just touch a metal surface before turning it on?

I have lived in Colorado and other southwest states, including Nevada. Usually, as far as electronics go, too much humidity is a concern, not the other way around. Dust will be your biggest speed bump in a dry climate. But, for acoustic guitars, dry climates are a concern. My dad always kept a compact humidor in his Martin case to keep the finish from cracking. Unless you have a bare-wood electric, the dry climate should not pose any threat to your instruments. Too much humidity will pose a threat. What I can say for sure is that I've had an Ibanez PF230 for over 30 years, and more than half those years were in dry climates. I never had any issue with that guitar, nor any of my amps (one of which I still have from 1981) from being in a dry climate.
